Legacy PCO mode in nrf conect SDK 1.7.1

[Vassilis]

Hi

I am evaluating nrf9160 with an nrf9160-DK on nb-iot in Greece. I am using the asset tracker application example.

I have an issue of DNS not resolving that is expressed with the  "getaddrinfo, error: -11" error in the debug info.

While using an engineering sample DK with SDK 1.4.0, following recommendations found on other posts I set the Legacy PCO mode and that solved the problem. I was able to connect to nrf Cloud and transfer data.. 

Now that I've got an new DK I am trying to use the latest SDK and modem firmware and I have the same problem.

Unfortunately it seems that this configuration option is not available in SDK 1.7.1   

Is it moved under another name ?

How can I overcome this?

Hi,

Both prebuilt 

nrf9160dk_asset_tracker_v2_debug_nbiot_legacy_pco_2021-10-20_d29f1dde.hex

and

nrf9160dk_asset_tracker_debug_nbiot_legacy_pco_2021-10-20_d29f1dde.hex

fail in different ways.

I have managed to build and run the asset tracker sample with SDK 1.4.0 but I cant find the PCO mode configuration in SDK 1.7.1

In the sample projects in Segger Embedded Studio though there is no differentiation on asset_tracker V1 and V2.. That is while in the prebuild hex files I can see a different V2 file, I don't know how to select the V2 sample source...
